I bought a set in July 2010 from NAMotorsports, however it looks like one of the drivers has failed, the LEDs look fine and all the wiring is ok. Can you supply drivers to fit this older model separately and if so how much are they? I assume the versions I have are just Lux H8 as opposed to V1/2/3. if it helps to identify them, in addition to the driver there is a separate fuse block in the wiring. thanks
